To all 'whom 'it may cci-noem y Be it known that I, Mn'rnew H. Armero;

'o eitizeno the. United States; residing at Butte,in the county of Silverbow and State of Montana, have invented certain new and useful improvements. in Lubricating De vices, of which the .following is e specification.

Tliie invention Vrelates, to improvements inl lubricating devices, and has for itl object to provide an improved lubricating device which will capable of attachment in any bearing, journal, or other rictionallyqeonmeting surfeees, vvhere lubrication is required.

Another object is to provide a lubricatingv device which will .permit the ready insertion of en oil spout orA rease gun, end'will prevent theentranee o dust-,or dirt.

Other objects'fw'ill be made apparent and set `forth in the following specification and accompanying drewin'g, in whichH Figure l is e longitudinal Aseetion of iny improved devofej-ehowing 'the semein closed position; Fig. a vievvv similar to Fig.` l',

inserted tlieretllroiigli Fig; 3, an inverted plan View of Fig. 1;Fig14 e transverse seeig. Q; and rig.A a side elevation-of o.' modiicetion.

Like numerals refer to like elen'ientsr throughout the drawings, in which- 110 designates'e plug having s. dependin sleeve .ll externally threaded, as indicate at 12. The plug is formed with a iienged head 1i centrallyapertured at 14. Secured to the heed 13 and de ending downwardly therefrom 'inside the s eeve'll is the yoke 15 having thearms 15. This yoke is provided with ari-enlarged portion 16 intermediate the. arms l5. A -eap17 haring the apertures 18 embracing the arms 15 of the yoke l5 is slidably mounteldron'the latter, es

shown in Figs. 1 and 2l cap 17 is provided With a. centrally raised 'portion 19 adapted to closely fit into and close the apert-lire 14 in the head 13 of plug 10. A spring 20 havingone end resting on and secured to the enlarged portion 16 of the yoke '15', ei:4 tends upwardly therefrom' and has its other 'extremity Seated in the centrally raised portion 19 of thev heed 17. ltwill oe seen that tliie spring normally tends toretein the Cap 14- in its closed position. as shown in i. 'The plug is adapted to 'De threededly at tuehed to e lubricating' aperture, the head o the spout 21,'the spring 20 -efiil force the cap l? beek to elosed position-#es indicated in Fig. l-in which position the entreneeo dustor dirt is prevented.

In' Fig. 5 l here illustratori e modification in which the plug 10 having the aper- .lo/cations tured head 13 and .externally threaded sleeve l1` is prorided 'with the yoke 1.5 having the arms- 1&7 depending downwardly from and secu'red to the sleeve 1.1. yoke 1.5 ispro'ridedfwith the enlarged porf tion 16 to which is secured end upon which reste' One-end of 'the spring''. A. oep l?" of. o. diameter. approximately equal to the external diameter-'of the sleeve il' is apex"- -tured so eS .to be slidab-ly mounted upon the arms 15 of the yoke 15. vThe upper, end of thefeprium 20' -is in oonteet with the under 17 Aand is. adept-ed to ret-ein surface oeap' the'seme iii closed posi ion, es illustrated in Fig. 5.
